Tudor 9401 movement question

9 posts in this topic

I am starting a Tudor 9401 build and have access to two different eta 27xx series movements (this is what will fit the dial).  The watch should have an eta 2776 which is a 21.6 bph with no date (cannot find a movement for sale).

I can get an eta 2772, 21.6 bph, with a date (for a good price); or eta 2771 28.8 bph, no date (for a little more money).

Would you choose the lower beat and incorrectly have a date setting? or higher beat with no date?

Thanks

Ah, the old movement problem....I feel for you.   I am having my entire project waiting for 2846 ETA's to come back in stock so I know how you feel.

 

Good luck and think someone knowledgeable will help.

Wouldn't it be possible to remove the date wheel and change the stem to a single pull, instead of the double pull on a date movement?

You can certainly remove the calendar works and then probably modify the setting lever spring so that it has only one detent for time setting only.

Thanks for the replies.  I am going to purchase the correct bph movement and have the calendar works removed during service.

eta does make a setting lever that fits all ETA 28xx models that is wind and time setting only, omitting the date pos.

You can also going off that little bump that makes the date detent, but it makes the action feel weird when you pull the stem.

Do you know if the setting lever for ETA 28xx will fit an ETA 27xx?

The eta 2846 is your best bet without a date which would have only winding and time setting but you can do it with any eta movement to make it time and winding set only, very easy to do and only need to swap out one part.
